We defeated Germany in WWII, but not the Nazi Party, which went on to form the EU and reorganize itself in Ukraine, credit Alan Dulles who exempted them from the Nuremburg trials. Ukrainian Nazis killed nearly 18,000 Russian speaking Ukrainians in the eastern provinces in the years prior to the Russian invasion.
Well, they missed one Russian Ukrainian, and elected him President instead. Now the Russians are committing a great many Nazi-like atrocities, such as confiscating children from their homes to be Russ-ified https://encyclopedia.ushmm.org/content/en/article/lebensborn-program
And how were those Russian-speaking Ukrainians killed? Shelling civilian neighborhoods? Lining them up against the wall and shooting them? All done by the invading Russians. I wouldn’t agree that any of that is any more than examples of the rotten things that people do to each other during civil wars. Nazis would go at it systematically, with ghetto-ization, slave labor and gas chambers, or at least a mass execution like in Babi Yar. Ironically, but there’s a memorial to Babi Yar’s dead in Kiev, which was damaged during the early days of the Russian Blitzkrieg.
The worst legacy that the Nazis left the world was their name, which is thrown around higgledy-piggledy to smear anything and everything from Trump’s wall and Israel’s victory in 1967, to the complex ethnic politics of the Ukrainian civil war and Russian invasion. It doesn’t describe anything anymore, but instead it is trivialized and morphed from a seriously evil ideology of dehumanization, with heinous practices, into a cheap insult.
The Nazis were racists and anti-Semites, while the EU imports Third World migrants, and censors anything smacking of racism, anti-semitism, Holocaust denial, homophobia, or Islamophobia (real or imagined).
So I wouldn't say the EU was Nazi. Germany (and much of Europe) essentially went from one anti-liberty extreme to the other.
They did a number on the Jews also. They murdered their share of them.
